ESPFlashDownload

I have just tried; I am able to erase the flash with ESPDownloadTool, both in SPI and HSPI, but if I upload the firmware via Arduino, the display has always the same problem.

I don't know I it works but, is it possible to reflash the bootloader?

Thanks,
Paolo

Not sure I can help but......................

Did you try the the ESPFlashDownload tool to try to erase the flash ? Has worked for me.

Did you have the com port selected on the tool ?

If you did use that tool and it failed to erase the flash, did it give you an error message ?

If I don't reply to your reply, it means I can't help and am leaving your response open for someone else to see.
